i .sash are formed with a l, WILLIAM J. BURTON, a i'nel t', while thetop rail k is formed with a.

cation, reference being had therein to t e accom `ianying drawings.

This invention relates more speciiically to an improvement in asheetunetal frame and sash; and it consists in the particulars morefully hereinafter described, and pointed out in the claims, referencebeing had to the aocoinpanying drawings, in which- .Figure 1 is aperspective view of a windowi'iamc and pivotcd self-closing sashembodying my invention. Fig. 2 is a vertical crosssection of Fig. 1.Fig. 3 is a horizontal section through the pivotal connection of thestile of the window-rai11e and side rail of sash on line :c in Fig. 2.Fie. 4 is a vertical section on line y y, F ig. 3, wit i the partsseparated. Fig. 5 is a central longitudinal section through the liturein the sash-cord. F 6 is an enlarged cross-section through the top railof the sash.

The window-frame is composed of a sill A, stile B, and a head-j amb C,each coin osed of sheet-metal plates bent into boX-lillie form 'andconnected together at the corners into a v rigid trame.

The sill is integrally formed with an upwardly-projecting portion a,forming a stop for the inner face of the bottom rail of the pivotedsash, and the head-jainb is formed with a downwardly-projecting portionc,

forming a stop for the rail of the pivoted sash.

Each stile ot' the -hanie is formed by doubling the metal upon itselfwith two inwardlyrejecting vertical ribs d d, and withinthe outer. taceof the top olds of the ribs thus formed are secured two metal strips Aee, .i; e outwardly-projecting portions of which forni vertical sto s forthe window-sash, one below and thel ot er above l the pivotal point. Thefree ends of these' strips are bent over to form inclined ledges e2 iorthe sash in its open position, as shown in Fie. 2.

is the sash, composed of to and side rails formed of sheet meta thedesired shape and secured to a rigid frame containing a panel glass n vother tire-resisting material.

The bottom rail f and the side rails h of the bottom, bent into etherinto of wire* Patented Nov. 13, 1906.

glass-receiving ebanthrougli-slot y', communicating with theglassreceiving channel i and adapted to form and State of Michigan, haveinvented certain new and useful lin rovenients in Metallic -VVindows, ofwhich t ie following is a s ecifil itself to form narrow channels j ateach side 1 The' slot is closed by means of a cap l, removably seof theinner end of the slot.

cured in the slot and having a central downi Wardly-projecting ribadapted to bear u on the upper edge of the glass panel, said rib ingformed by folding the sheet of metal from which the cap is formedlongitudinally upon itself, and yielding side portions at each side ofthe rib to en age the sides of the slot are formed by ben 'n the edgesof the metal outward or lateral y each way from the rib, thencedownward, the downwardly-extending edges Z narrow channels j. heengagement of the downwardly-extending ed es Z with the channels jprevents water om getting into the interior of the sash, and byproviding th cap with yielding sides it ma the slot and will then behel, in ace. v

The bottom ail of the sash 1s formed on the outsi de withr a dependingflange m, adapted to project down over an offset 'n formed on the sill,-thereby forming a weather-strip, and the top rail is formed upon theinside in like manner with a flange o, whichprojects upwardly. The sashis supported in the window-frame upon horizonte pivots, which areconstructed as follows: K

A pivot-hole is ta ped in each vertical edge portion of t e sasli)body,and to the reverse side of the edge portion --is riveted or otherwisepermanently secured a reinforcingplate g, provided wit an apertured bossv.

Directly opposite the pivot-holes p in the sash corres ending holes sare tapped in the stiles and t rough suitable reinforcing-` lates t,which are permanently secured to t ereverse fac-c of the stiles. Throughthese holes a pivot-pin u projects outwardly into thev pivotally subeing ada ted'to enter the said be ressed into IIO and have ascrew-threaded' engagement with the plate r only, whereby in turning thetogether at the meeting edges by fusible sol- .parted as soon as theheat softens the solder, -and the device is therefore far morevsensitive 5 5 yprovided with alined .-'the heat in the roorn.

screws with the screwdriver in one direction the will draw the plate ragainst the ,plate t an( hold the pivotpin in the projected position,(shown in Fig. 4,) while, on the other hand, they will cause thepivot-pin to recede in to the stile if turned in the opposite`direction. To prevent the screws from. Wholly unscrewing from the plate7', the'iree ends are upset.

lt will be seen from. Figi 2 that if the sash is in the o en positionthe heads of the screws w are er 'ectly accessible, and while the sashis in t is position it can therefore 'be readily disengaged from thepivots and taken out for `the purpose of glazing or for any otherpurpose and as readily be put into place again. When the sash is closed,the screws w are covered by the sash .and cannot be operated1 inconnection therewith it will be noticed'that the open position of thesash is perfectly defined by the litiges e2, which forni between them agnidew: "orthe sash in taking it out or utting it back again. The sashis ovcrba sneed on its pivot, so that it is self-closing and locksitself closed by means of a springlatoh G, secured to the top rail o1"the sash and adapted to engage with a keeper ii, secured to theliead-jami). The sash is adapted to he drawn open and held in its openposition mea-ns of a chain or wire cord l, secured to the latch on thetop rail of 'the sash and adepted to be engaged with a hook at its lowerend, and in order to yclose the sash automatically in caseof lire thecord or chain lis mede in two sections, connected toeether bye iixture(l, composed of 'two thinililelile halves, joined der and forming thehousing for a coil-spring' K, inclosed therein under compression. Thetwo meeting edges of the fixture torre between them an annular channelof tf-sha ed cross-section which receives the fusible sol er, endthereby exposes it to the direct action. of Since the inclosed spring isunder considerable compression, it will be understood that the halveswill be to heet and quicker to act than upon the solder alone.
